Key Highlights BRICS Summit 2026 will be held in New Delhi from September 11 to 13. Bharat Mandapam at Pragati Maidan will host the summit. September 11 has been declared a holiday for central and Delhi government offices. Delhi schools are also scheduled to remain closed on September 11. Security arrangements have been intensified across the capital. Foreign delegations are expected to stay at designated hotels in Delhi and NCR. Nearly 4,800 traffic personnel are expected to be deployed for traffic management. Delhi Police has advised commuters to use Metro and plan journeys in advance. Why Delhi Is Declaring a Holiday on September 11 The decision to close government offices on September 11 has been taken to reduce pressure on Delhi's roads and security infrastructure during the arrival and movement of foreign delegations. Both central government offices in Delhi and New Delhi and offices under the Delhi government, including autonomous bodies and public-sector undertakings, have been ordered to remain closed. Authorities expect the move to reduce the number of daily commuters on roads during one of the busiest days of the summit preparations. The summit's schedule coincides with the weekend on September 12 and 13, meaning the government holiday is expected to help authorities manage traffic and security during the three-day event. Delhi Schools to Remain Closed The BRICS Summit will also affect educational institutions in the capital. Schools across Delhi are scheduled to remain closed on September 11 in view of the BRICS Business Forum and the BRICS Leaders' Summit. The decision is aimed at reducing movement on roads and easing the pressure on transport networks during the high-security event. Students and parents have been advised to check instructions issued by their respective schools regarding classes and academic activities. International Delegations to Stay at Luxury Hotels The arrival of international dignitaries is expected to result in heightened security around several luxury hotels in Delhi. According to reports, foreign delegations are expected to stay at around 10 designated luxury hotels, with most located in central Delhi and another in the Saket area. Security arrangements have been intensified around these locations because of the movement of VVIP convoys between hotels, the airport and the summit venue. The movement of these convoys could result in temporary stoppages of traffic even on roads that are otherwise open to the public.(Read More : BRICS Summit 2026: Delhi Police Issues Traffic Advisory, Check Affected Routes) Nearly 4,800 Traffic Personnel to Be Deployed Delhi Traffic Police has prepared an extensive traffic-management plan for the summit.
